Tullow to cough up $393m tax - Loses legal battle against GRA

In an arbitral award dated September 22, 2026, the tribunal based in London, United Kingdom, held that the tax assessment was reasonable, did not breach any law, such as the Petroleum Income Tax Law, PNDCL 188, as well as the Petroleum Agreements (PA) between Ghana and TGL and other partners.

The International Court of Arbitration of the International Chamber of Commerce (ICC) has dismissed a challenge to a $393 million tax assessment liability and a penalty on Tullow Ghana Limited (TGL) by the Ghana Revenue Authority (GRA).

The decision of the tribunal, which is final and binding means that there is no legal hurdle currently impeding Ghana from enforcing the $393 million tax assessment.
